Topic: Best Bolt On's for performance?

[Main One]

I'm thinking if you want to go with a cam, this one would be a better choice for your application/desires:

I think the root of my evil is the 4.56's.  I have the low end (with them), but I never got used to the higher RPMs at highway speeds.  I stopped by my tranny shop to get my reciept (warranty for rebuild) and my tranny man just happens to have some 4.10's out of a Yukon XL that I think will fit.  May do me a swap cheap and install if they fit.  He says they will.  If I change the gears, then I think that changes my cam direction.  We'll see.

I think that will help a good deal.  May want to change your shift points with the superchips, but I'd think with the 4.10s you could be able to downshift into 2nd at 75 and hold it to at least 80.

Sounds like you need to teach me how to drive too!!

This sounds about right to me also. My tires are 32" and I turn about 2150 rpms at 70 mph; you'll turn slightly less than that with your 33s (that's what I remember you have). And don't forget to adjust your speedometer with a GPS unit.

4.10s are typically recommended for 33" tires. Maybe we got to the correct conclusion; try the 4.10s and then see how you like the towing. You might be less satisfied with the off-the-line speed after getting used to the 4.56s but there are other ways to address that if you decide you want to (converter; cam, not so much).

I still think a cam along the lines of what we originally recommended would be good but knowing you are reluctant to rev the engine up into its higher torque band makes them less attractive than the alternative that M1 posted. That one will gain hp/torque starting lower in the rpm range at the expense of the upper-rpm range that the original recommendations would give you. You would likely not have much luck finding that one used, though.

I think that's probably less of a concern than ultimately making the right choice, though.

Think I'm going to go the 2500 route.  Found an '05 low mileage one locally that I like.  It's black, but I can live with that.  Just have to reel in those folks that have offered to buy mine in the past.  Maybe by Bratfest!!??

One of the most effective bolt on performance upgrades there is.
Unbolt the plate(s) and bolt it(them) onto a 2500 with an 8.1L.

That's what I'm thinking too!!

I'm happy with my 2500, but I bought it to pull our TT

That is one of the main reasons I was looking for a little more power.  I pull a TT also at around 5K loaded and we are wanting to take it out a more frequently.
